APPARATUS FOR GIVING EASE TO THE ABM IN WRITING.

`\ Specicaton of LettersPatentNo.v 8,065, dated .April` 29, 1851.

To all 'whom it may concern: i i

Be it known that we, JOSEPH Gg GOsHoN, of Shirleysburg, in the countyofHunt-ingdon and State of `Pennsylvaniaand WIL- LIAM H. TOWERS, ofBucyrus, inthe county of the penman when writing. F ig. 2, is aAperspective view of the supporter,` Fig.` 3, is a vertical Section `ofditto.

Where the same letters occur on the above figures they indicate thesameparts.

The nature of our invention and improvement consists in theconstructionof `a flexible arm supporter,` or rest,`so formed and shaped asto litthe arm of the penman`be low the elbow joint, and serve as a ieXiblesupport and rest, on which the arm is sup` ported and balanced andpermitted to move or turn with the utmost freedom and ease to thewriter,-tlius effectually preventing numbness of the arm and theconsequent `contraction of the `muscles of the fingers,

aswell as entirely relieving the arm from any cramping or stiffnessproducedY by constant writing which often happens to most penmen. Thiseect is produced by the inflexibility of the desk or bearing of the armof the writer. This flexible or elastic supporter consists of a`circular metallic plate A provided with an opening in its center andmade concave so as to t the conveXity of the arm. To the underside ofthis plate and near its periphery there is attached by` any convenient"means a spiral spring B which projects downward 1n a regular spiralline7 somewhat resembling an inverted cone, and is connected to a smallplate C,or but- "ttn exactly in the center and beneath the concaveplateA,`-V-the plate or button C, at the lower end ofthe springB, forming therest on which the `flexible supporter turns and moves with the motion ofthe arm. Over the upper part of the concave metallic plate is secured apiece of leather having an opening therein corresponding with that inthe concave plate. Around and beneath the spiral spring there isalsoconfineda piece o f leather or other material for the purposeofinclosing the spring and givinga neat appearance to the supporter.`

i On either side ofthe supporter .anddiaf metrically` opposite are twospring` plates D made of thin steel attached to the cancave plate A andprojecting upward and lapping each other, and areeach about asemi-circle equal to half the circumference of the arm,

`and covered or ornamented with silk, and

are for the purposeof embracing the arm and confining the .supporterthereto, while the penman is writing and preventing its sliding ormoving onthe arm when once adjusted. i

There is a thin` plate E placed across the diameter of the centralopening `of Athe metallic plate A, and corresponding with the concavityof the same, and is for t-he purpose of preventing the lower portion ofthe spiral spring` B projecting through the cen tral opening in theconcaveplate when contracted by the pressure of the arm thereon,

and thus the action ofthe spiral spring is prevented from interferingwith the arm.

This supporter when used is placed upon `the arm of the penman aboutmid-way between the elbow joint and joint connecting the hand with thearm, adjusted as desired and confined by the semi-circular springs Dwhich embracethe arm on either side and hold it secure. Or straps may bemade to pass over the arm and buckle or otherwise instead of thesemi-circular springs.

This supporter may be made of any desired shape, size, `and material andornamented in any desired manner, and will be found to be of greatadvantage to the penman, in as much as it imparts perfect ease,lightness, and freedom to the arm, and preserves the sleeve oft-he coator other garment from rubbing and wear, the arm being elevated from thedesk and supported by the flexible support.

. This supporter may `be made entirely of gum elastic or india rubber,and inflated -Vwit-h air, to give it anyrequired degree of elasticity,and provided with a band or strap to embrace the arm and hold itsecurely thereto. i

Having thus described our invention and improvement, and shown theapplication of the same to the `arm of the penman, what we claim as ourinvention and desire to secure by Letters Patent7 is- Constructing anarm supporter or rest so formed and shaped as to -fit the arm below theelbow joint, and serve as an elastic or flexible support or rest onwhich the arm of the penman is supported and balanced and permitted tomove or turn with the motion of the arm, with the utmost freedom andease to the writer, by which all numbness.

contraction of the muscles of the lingers, and

erampness or stiffness of the arm is etlec-y tually prevented and thearm rendered free in its movement and Linder the complete control of thewriter, as fully described and represented.

In testimony whereof we have hereunto l5 signed our names before twosubscribing witnesses.
